Final answer:
The assertion that the feminist movement promoted more confining underwear is false. The movement encouraged less constrictive and more practical clothing, in line with the push for greater personal and social freedoms for women.
Step-by-step explanation:
The statement that changes in women's clothing in the 1960s and 1970s attributed to the influence of the feminist movement include more confining underwear is FALSE. In reality, the feminist movement of the 1960s and 1970s played a significant role in advocating for less constrictive clothing for women, paralleling their broader pursuit of social and personal freedom. During these decades, many women adopted fashions that were less restrictive and more practical, reflecting their increased confidence and the new opportunities being afforded to them, such as equal opportunity employment and access to education.
Feminist activists often protested against instruments of women's oppression, which included confining clothing like corsets, girdles, and restrictive bras. This led to more comfortable and liberal attire, empowering women to move freely and be less bound by traditional feminine standards. The feminist art movement also contributed to altering fashion norms by breaking down gender stereotypes and conventional ideals of female beauty, while fostering a culture where women's contributions to the arts were more validated and respected.
